E-Verser Dr. Mitchell writes in from the UK:

Thought you might find this interesting. My dad and I visited a very beautiful village called Edensor near the stately home of Chatsworth House in Derbyshire. Chatsworth is the ancestral seat of the Dukes of  Devonshire (of the Cavendish family) and the grounds were landscaped by the renowned Capability Brown.

Anyway, Edensor to this day houses the residential community that work the estate and includes an intrinsic parish vicar at the archetypal English church. In the churchyard there is an enclosure wherein reside the departed members of the Cavendish pedigree. John F Kennedy’s sister Kathleen married the brother of the Duke (who carried the title of Marquess of Hartington) in early 1940s and passed away in 1948 at the tender age of 28. During a state visit to the UK in 1963, JFK himself flew into Edensor to pay his respects, and this detail is commemorated also, in light of his own tragic early death and goodly reputation.

A real surprise for me.
